b.
Touch one multimeter test probe to contact A of one connector and touch remaining probe to
contact A of connector at opposite end of cable Multimeter must indicate continuity If it doesn't,
there is an open in one or both connectors or in wire
c.
With one probe still at contact A of one connector, touch second probe to each remaining contact of
second connector In each of these positions, multimeter should indicate greater than 10 ohms If
reading is less, cable is shorted
d.
With one probe still at contact A, touch second probe to connector housing Multimeter should
indicate no continuity
e.
Repeat steps b through d for each remaining wire In cable. Refer to figure 4-5 for correct ongoing
and destination of each wire
f.
If an open, short or ground fault is detected In cable, replace cable or notify higher level of
maintenance
Figure 4-5. Power/Control Cable and Auxiliary Cable Wiring Diagram.
4-20.
Control Cable Testing. (See figure 4-6). The control cable connects the PDU at J6 to the ICC or
CRG. A continuity test is used to detect faults In the cable.
a.
Set multimeter controls for continuity testing.
b.
Touch one multimeter test probe to connector P5 contact A and touch remaining probe to connector
P6 contact A. Multimeter must indicate continuity. If It doesn't, there is an open in one or both
connectors or in wire.
c.
With first probe still at P5 contact A, touch second probe to each remaining contact of P6. In each of
these positions, multimeter should indicate no continuity If continuity exists, cable is shorted.
d.
With first probe still at P5 contact A, touch second probe to connector housing. Multimeter should
Indicate no continuity.
